Correct answer is 50% .

Men with X-linked disorders transmit the gene to all their daughters, who are carriers, but never to their sons. Women who are carriers of an X-linked disorder have a 50 percent chance of transmitting the carrier condition to their daughters and a 50 percent risk of transmitting the disease to their sons.
